+
+Content includes, but is not limited to, source code, object code, documentation and other files maintained in the
+Eclipse Foundation source code repository ("Repository") in software modules ("Modules") and made available as
+downloadable archives ("Downloads").
+
+*   Content may be structured and packaged into modules to facilitate delivering, extending, and upgrading the Content.
+    Typical modules may include plug-ins ("Plug-ins"), plug-in fragments ("Fragments"), and features ("Features").
+*   Each Plug-in or Fragment may be packaged as a sub-directory or JAR (Javaâ„¢ ARchive) in a directory named "plugins".
+*   A Feature is a bundle of one or more Plug-ins and/or Fragments and associated material. Each Feature may be packaged
+    as a sub-directory in a directory named "features". Within a Feature, files named "feature.xml" may contain a list
+    of the names and version numbers of the Plug-ins and/or Fragments associated with that Feature.
+*   Features may also include other Features ("Included Features"). Within a Feature, files named "feature.xml" may
+    contain a list of the names and version numbers of Included Features.
+
+The terms and conditions governing Plug-ins and Fragments should be contained in files named "about.html" ("Abouts").
+The terms and conditions governing Features and Included Features should be contained in files named "license.html"
+("Feature Licenses"). Abouts and Feature Licenses may be located in any directory of a Download or Module including, but
+not limited to the following locations:
+
+*   The top-level (root) directory
+*   Plug-in and Fragment directories
+*   Inside Plug-ins and Fragments packaged as JARs
+*   Sub-directories of the directory named "src" of certain Plug-ins
+*   Feature directories
+
+Note: if a Feature made available by the Eclipse Foundation is installed using the Provisioning Technology (as defined
+below), you must agree to a license ("Feature Update License") during the installation process. If the Feature contains
+Included Features, the Feature Update License should either provide you with the terms and conditions governing the
+Included Features or inform you where you can locate them. Feature Update Licenses may be found in the "license"
+property of files named "feature.properties" found within a Feature. Such Abouts, Feature Licenses, and Feature Update
+Licenses contain the terms and conditions (or references to such terms and conditions) that govern your use of the
+associated Content in that directory.

+
+### Use of Provisioning Technology
+
+The Eclipse Foundation makes available provisioning software, examples of which include, but are not limited to, p2 and
+the Eclipse Update Manager ("Provisioning Technology") for the purpose of allowing users to install software,
+documentation, information and/or other materials (collectively "Installable Software"). This capability is provided
+with the intent of allowing such users to install, extend and update Eclipse-based products. Information about packaging
+Installable Software is available at
+[http://eclipse.org/equinox/p2/repository_packaging.html](http://eclipse.org/equinox/p2/repository_packaging.html)
+("Specification").
+
+You may use Provisioning Technology to allow other parties to install Installable Software. You shall be responsible for
+enabling the applicable license agreements relating to the Installable Software to be presented to, and accepted by, the
+users of the Provisioning Technology in accordance with the Specification. By using Provisioning Technology in such a
+manner and making it available in accordance with the Specification, you further acknowledge your agreement to, and the
+acquisition of all necessary rights to permit the following:
+
+1.  A series of actions may occur ("Provisioning Process") in which a user may execute the Provisioning Technology on a
+    machine ("Target Machine") with the intent of installing, extending or updating the functionality of an
+    Eclipse-based product.
+2.  During the Provisioning Process, the Provisioning Technology may cause third party Installable Software or a portion
+    thereof to be accessed and copied to the Target Machine.
+3.  Pursuant to the Specification, you will provide to the user the terms and conditions that govern the use of the
+    Installable Software ("Installable Software Agreement") and such Installable Software Agreement shall be accessed
+    from the Target Machine in accordance with the Specification. Such Installable Software Agreement must inform the
+    user of the terms and conditions that govern the Installable Software and must solicit acceptance by the end user in
+    the manner prescribed in such Installable Software Agreement. Upon such indication of agreement by the user, the
+    provisioning Technology will complete installation of the Installable Software.
+
+### Cryptography
+
+Content may contain encryption software. The country in which you are currently may have restrictions on the import,
+possession, and use, and/or re-export to another country, of encryption software. BEFORE using any encryption software,
+please check the country's laws, regulations and policies concerning the import, possession, or use, and re-export of
+encryption software, to see if this is permitted.
